Circuit Playground Express takes on the ARP Odyssey

The Circuit Playground Express goes duophonic implementing a tiny number of the features of the ARP Odyssey with the help of a little bit of external electronics:


This one doesn't use the CPX speaker, the audio output from the external mixer circuit is being amplified. It's also shown on a Telequipment S51B oscilloscope (the one with the broken trigger function).
